Since its HDD is dying, it will need a new drive. 512 GB should be a
good enough size. I'd like to reuse this drive for other computers
(Windows, Mac OS, Linux, etc. on desktops and (laptop/notebook)s) too if possible if MBP dies later on. Is Crucial brand good as shown in http://guides.crucial.com/c/MacBook_Pro_15"_Core_2_Duo_Models_A1226_and_A1260 ?
Thank you in advance. :)

What about v10.8.5/Mountain Lion?
the os version makes absolutely no difference. that's like asking if a
hard drive work with mountain lion. of course it would.

There is a difference and it pertains to TRIM.

The statement was made that OS version did not make ANY difference with regards to SSD support. I provided evidence that there were differences
with regards to 3rd party SSDs which is exactly what is being discussed
here.
"needed" is the keyword here. yes, an SSD will work without TRIM. But enabling TRIM is very advantageous which is why APPLE has been enabling
it on its own drives for years, and has now made it possible to do this
for 3rd party drives.
Modern drives are no different than older drives with regards to
advantages of TRIM. (except very old SSDs didn't know about TRIM, but
that would not be the case for current SSDs you buy today).
It is you who refuses to understand how disk drives work and in
particular how SSDs work
and why TRIM is beneficial because no SSD
understands the file system and whether a disk block is part of a
deleted or active file. TRIM makes explicite statement to SSD that a
disk block is free, so when all blocks part of a SSD page are markled
free, the page can be recylced and made available for new writes and
more importantly, those TRIMmed blocks inside a page are not propagated
when 1 block in that page is being updated by OS , requiring the page to
be rewritted elsewhere. (this has implication as secure erase no longer available, so data in blocks from deleted files no longer keeps getting copied all over the place).

Prior to Yosemite, you coud install a hack to the kernel extension which allow TRIM on non Apple SSDs.
At Yosemite, that extension required you turn off kernel extension verification as part of the boot-arg in NVRAM. (forget the specific term
that had to be used).
Starting at either 10.5.2 or 10.5.3, Apple introduced a line command
that turned on TRIM on any SSD drive (irrespective of make) with no
garantees it will work. This removed the need for the kernel extension
hack and the turning off of kernel extension verification in NVRAM.
you didn't provide any such thing.
apple tests trim with its own ssds, which have apple custom firmware so
that trim works properly.
there are ssds with buggy trim implementations, where problems can
occur. do you want to trust your data to a buggy ssd?
modern ssds have their own garbage collection. trim is nice but it's
not required.
you didn't provide any such thing.
I'll repeat again, since you have hard time with this.
Prior to Yosemite, you could enable TRIM with a kernel extension which
hacked the SSD disk driver.
At early Yosemite, that extension required you to disable kernel
extension verification to function. (boot would hang as it switched from
EFI disk driver to the OS-X disk driver which would fail verification).
At about 10.5.3 or .2, Apple introduced an unsupported utility that
enabled TRIM in 3rd party drives without needing that extenstion hack.
So yes, what version of OS-X you have matters with regards to 3rd party support.
apple tests trim with its own ssds, which have apple custom firmware so that trim works properly.
Breaking news: Apple tests its hardware.

Yosemite (macOS 10.10.x) came out in 2014 afair, Mac OS X 10.5.x
(Leopard) came out in 2007 (which I think is prior to Yosemite)

If TRIM is so useless as you proclaim, why then did Apple implement is rapidly when it started to ship machoines with built-in SSDs ?

Are you denying that handling of TRIM has changed through different OS-X versions ? Are you denying Apple introduced kernel extension checks with Yosemite (which disabled popular TRIM enabler) and that Apple then
introduced a TRIM enable utility for 3rd party SSDs in one of the
Yosemite sub versions ?
Which was almost 100% of the time a terrible idea that destroyed SSDs.
Look who is spreading FUD. SSDs have long ago started to support TRIM.
If you bought a modern SSD you wouldn't have problems.

FUD again. If you enabled TRIM on a drive that didn't support it, you woudln't lose your data, worse case, you would need to reboot after
doing a delete that would send TRIM commands the drive didn't know how
to process. Normally, those drives should have ignored the TRIM commands
or you shouldn't have enabled it if you had old SSDs.
Most drives do not need TRIM
And most iPhones don't need a protective covers, yet it is the
recommended practice to protect the iPhone. Same with SSDs. They may
function without TRIM enabled, but it is recommended to enable it.

Every time some one talks about an SSD you pop up like the world's most annoying prairie dog and start in on your song and dance about TRIM.
TRIM is not the topic under discussion. At All.
Your idiotic parroting of 'facts' you have been shown over an over to be false is tiresome.
